LQH44NN4R7M03L - Murata Electronics

LQH44NN4R7M03L Frequently Asked Questions (FAQs)

• What is the recommended land pattern for LQH44NN4R7M03L?
  Murata recommends a land pattern with a pad size of 2.5mm x 1.8mm, and a spacing of 1.5mm between pads. Refer to the Murata Land Pattern document for more details.
• Can I use the LQH44NN4R7M03L in a high-temperature environment?
  The LQH44NN4R7M03L is rated for operation up to 125°C, but derating is required above 85°C. Consult the datasheet for specific derating curves and temperature-related information.
• How do I handle the LQH44NN4R7M03L during PCB assembly to prevent damage?
  Handle the component by the edges, avoid touching the component body, and use an anti-static wrist strap or mat to prevent ESD damage. Follow standard PCB assembly and handling procedures.
• What is the equivalent series resistance (ESR) of the LQH44NN4R7M03L?
  The ESR of the LQH44NN4R7M03L is not explicitly stated in the datasheet, but it can be estimated to be around 0.1-0.2 ohms based on similar inductor models from Murata.
• Can I use the LQH44NN4R7M03L in a high-frequency application?
  The LQH44NN4R7M03L is designed for general-purpose use and has a self-resonant frequency of around 100 MHz. It may not be suitable for high-frequency applications above 50 MHz. Consult the datasheet and Murata's high-frequency inductor offerings for more suitable options.
